Another problem is that it's static; my understanding is the extension creator needs to make a new list, get it approved by Google, put it in the repository, and get the user to download the update, before a new ad is blocked. Probably requires a restart of the browser, also. Not sure if it removes the ability for the user to on-the-fly add any blocking, but I suspect it does.
